I have reverted your changes so that you can start with a clean slate to add your cycle route.

Hi, there is a specific way to add a cyle route to osm.
Please read the following and amend you route accordingly.
osm.wiki/Cycle_routes

Hi, you appear to have duplicated the waterway.
One is named Arroyo Lerma Santiago and the other Arroyo Rio Lerma Santiago, Arroyo Rio Lerma Santiago is drawn in the wrong direction. Waterways are drawn in the downstream direction they flow.
I was going to map it to the River Río Grande de Santiago but want to know what the correct name is.

Correction...
close north of Birdsville should read close north of Betoota

Hi, the multipolygon is invalid in osm as sides of rings cannot be shared.

These road extensions appear not to exist either

Nothing seen on latest Copernicus Browser image either.

Sorry, I see the source tag now.

Hi, some of the roads have a source name tag. If you change the name you need to delete the old source tag or add the source you are using to that tag. You can add the new source to your changeset comment too or instead.
What is your source for the name changes?

You have missed renaming a section of the offramp as part remains as Fitzgeralds Road Offramp.

Is the renaming correct. All residential and businesses still use Old Geelong Road as their address in the part you have renamed.

Is this a proposed road construction?
No changes visible on imagery.

These changes will be reflected on the Qld Globe soon and I guess eventually find their way into national datasets.

The Landsborough Channel was not named correctly on the GA Surface Hydrology Lines dataset.
I inquired and subsequently the Qld Spacial Help Centre determined ...

The Thompson River confluence begins approximately 12 km north of Muttaburra (see survey plan PL44).

At this point, it meets Landsborough Creek, Dotswood Creek, and Cornish Creek.

The watercourse identified as the Landsborough Channel, situated east of Muttaburra and flowing north to south, has been traced northward to its confluence with Landsborough Creek. To the south, it extends 16 km, where it joins Bangall Creek before reconnecting with the Thompson River.

I have taken these changes into account with mapping of the Landsborough Channel.

We don’t have gas stations in Australia.
Should this be shop=fuel instead?

You have deleted the outer scrub boundary
https://overpass-api.de/achavi/?changeset=162763421 leaving two inners that osmi spotted
https://tools.geofabrik.de/osmi/?view=areas&lon=145.31352&lat=-37.91011&zoom=17
As the boundary was the 16th version it would be better to revert that part of the changeset.
I can try if you are unsure how to do it using Josm.

Hi
small osmi problem here
https://tools.geofabrik.de/osmi/?view=areas&lon=152.93959&lat=-27.54632&zoom=17

The semicircular part appears to have its roof line integrated into the rest of the building so having an outer encompassing the entire building with two inners would seem a good way to map it.

Hi
the complexity of the mapping has some errors
